Others have talked about backup/restore, but the easiest way is to put
the old drive into the new system.
On F9
In the new system with old drive, or on the old system before moving
the
drive, boot into rescue mode:
at the prompt:
rm /mnt/sysimage/etc/udev/rules.d/*persistant*
/mnt/sysimage/etc/X11/xorg.conf
exit
That will eliminate MOST of the hardware configurations, and they will
be rediscovered.
You may or may not need to run system-config-display after booting from
the drive. F9 versions of the X server do not 'need'
/etc/X11/xorg.conf
to run, but may need it to run properly.
That is a 10 minute exercise vs the 3-8 hours for the backup/restore
method.
Having said that, there may be valid reasons to spend the time, and
backups are ALWAYS a good thing. YMWV
Good Luck!
Don't forget about rebuilding the initrd if the driver for your hard
drive controller changes. (I had this happen with PATA controllers.)

here is what I use -- also from rescue -- F9 only -- when I know the
controller may be different -- probably overkill:
after chroot to /mnt/sysimage
#!/bin/sh
kernel=`ls /boot/vmli* | awk -F\- '{printf("%s-%s\n", $2,$3)}'`
initrd="/boot/initrd-${kernel}.img"
rm $initrd
/sbin/mkinitrd --preload=ehci-hcd --preload=ahci --preload=libata
--preload=jbd --preload=ohci-hcd --preload=uhci-hcd
--preload=scsi_wait_scan --preload=usb-storage --preload=scsi_mod
--preload=sd_mod --preload=pata_amd --preload=ata_generic
--preload=pata_cs5536 --preload=pata_acpi $initrd $kernel
#
well, I should mention that this only works with one kernel, should be:
kernel=`ls /boot/vmli* | tail -1 | awk -F\- '{printf("%s-%s\n", $2,$3)}'`
to be generic
